DB+ Series speakers bring rich, full-range Polk sound to cars, boats, motorcycles, and ATVs, with marine-tough construction and a universal fit that makes better audio easy.
Ultramarine-certified MM1 Series speakers are Ultra-Marine Certified with an IP56 rating, using corrosion-resistant materials, reinforced construction, waterproof surrounds, drainage, and salt-fog, UV, and humidity testing to stand up to life on the water.
Polk speakers are engineered to catch distortion, vibration, and mechanical issues before they reach your system, with Klippel testing and proven design processes that help keep the sound clean when the ride gets loud.
Great Sound for All
Polk was built on a simple belief: great sound should pull people in, not keep them out. Since 1972, we’ve been making speakers and sound systems that deliver the experience, not the ego, with thoughtful engineering, powerful performance, and sound made for the way people actually listen.
